Title: Improvements in universal joints
IPC: F16H1/00
Filed: 1960-08-18
Abstract: 964,694. Universal joints; toothed gears. G. A. WAHLMARK. Aug. 18, 1960 [April 12, 1960], No. 28657/60. Headings F2Q and F2U. A constant velocity universal joint of the gear type comprises internal and external gears 22, 24 having generally diamond-shaped teeth. The teeth may be formed by cutting right-hand helical gear teeth on a gear and subsequently cutting left-hand gear faces on the same teeth. Each tooth is thus formed with pairs of oppositely formed helical drive faces 46 diverging axially from a central radial plane b. An arcuate surface 56 forms the juncture between adjacent helical faces. Each tooth tapers towards its tip, and the faces are slightly " crowned." Either or both gears may pivot, and each gear does so about an axis in the plane of the other gear and within its pitch circle, but not necessarily about a diameter of the other gear. Specifications 835,936 and 892,714 are referred to.

Filed: 1970-06-15
Abstract: 1314854 Lasers COMPAGNIE GENERALE D'ELECTRICITE 15 June 1970 [20 June 1969] 28971/70 Heading H1C [Also in Division C4] A process for improving after initial crystal growth, the light emissive properties of a monocrystal doped with a material which renders the monocrystal laser active comprises heating the monocrystal in an oxidizing atmosphere at a temperature equal to 800‹ C. or between 800‹ C. and a temperature close to the melting point and at which an internal modification of the structure occurs. The duration is preferably such as to optimise the emission, and is determined experimentally by varying one of duration and temperature in the treatment of a number of identical monocrystals. The gain initially increases with duration of treatment but may subsequently decrease past the maximum value (Fig. 1 not shown). The crystal may be subjected to further thermal treatment in a reducing atmosphere and the monocrystal may be YAG and its m.p. 1970‹ C. Restoration to maximum gain or further increase in gain may be obtained by a subsequent treatment in a reducing atmosphere, during which the rod temperature may be changed. With YAG, temperatures may be 1100‹ to 1500‹ C. with 12 to 24 hrs. duration, the duration being one to 10 days.
